Description

The project contains the VHDL code for a complete
DECPDP-11
system: a PDP-11/70 CPU with memory management unit, but without
floating point unit, a complete set of mass storage peripherals (RK11/RK05,
RL11/RL02, RK70/RP06, TM11/TU10) and a basic set of
UNIBUS
peripherals (DL11, LP11, PC11), and last but not least a cache and
memory controllers for SRAM and PSRAM.

Re-discovered a pile of PDP-11 manuals in a forgotten box full of old paper work. This triggered the idea, and with simh, ghdl and bitsavers at hand, 2.11BSD as target OS and a 11/74 picture as desktop background it quickly became a project.
